I have the following setup:
[phil@thinkpad ~]$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 238,5G 0 disk ├─sda1 8:1 0 52,3G 0 part ├─sda2 8:2 0 111,8G 0 part /home ├─sda3 8:3 0 954M 0 part [SWAP] └─sda4 8:4 0 50G 0 part / sr0 11:0 1 1024M 0 rom
sda1 : root partition of ubuntu sda2 : home partition of ubuntu & arch sda3 : swap partition of ubuntu & arch sda4 : root partition of arch
what i want to achieve : delete the ubuntu root partition (sda1)
what is my problem / fear : when i boot up, GRUB is displayed to choose from either arch or ubuntu. This is the grub installation from ubuntu, so if i delete the ubuntu root partition (sda1), the grub installation is also gone, right?
-> How can I overwrite the (ubuntu) grub installation with the other (arch) grub installation?
Thanks in advance!
